DESCRIZIONE
Provided is a method of producing a laminated body, the method comprising a coagulant solution deposition step of depositing a coagulant solution on a fiber substrate, and a coagulation step of forming a polymer layer on the fiber substrate by bringing a polymer latex into contact with the fiber substrate having the coagulant solution deposited thereon to cause a polymer to coagulate. As the coagulant solution, a solution obtained by dissolving or dispersing 0.2 to 7.0% by weight of a metal salt as a coagulant and 0.1 to 7.0% by weight of an organic acid in a solvent is used. In the method of producing a laminated body according to the present invention, the metal salt is preferably a polyvalent metal salt. In the method of producing a laminated body according to the present invention, the organic acid is preferably an organic acid having at least one group selected from a carboxyl group, a sulfo group, a hydroxy group, and a thiol group. In the method of producing a laminated body according to the present invention, a polymer constituting the polymer latex is preferably a nitrile rubber. [Image Omitted]
